Table 2. Selected genes differentially expressed in the HP0906 mutant.

Only genes with fold-change ≥2.00, P ≤0.05 and known function are listed in this Table. Fold-changes and P values were calculated based on three independent biological replicates, as described in Methods. Genes discussed in this paper are shown in bold type.
